Charles H. Spurgeon on Psalms 119:56

This I had, etc. The Rabbins have an analogous saying, The reward of a precept is a precept, or, A precept draws a precept. The meaning of which is, that he who keeps one precept, to him God grants, as if by way of reward, the ability to keep another and more difficult precept. The contrary to this is that other saying of the Rabbins, that the reward of a sin is a sin; or, Transgression draws transgression. Simon de Muis, 1587-1644.
